Customer Review:
Kanishk says, “Let me start of by congratulating the entire Edureka team for putting together such an amazing content for their courses. I am enrolled in their live course and my learning experience has been phenomenal. I tried learning Linux Administration on my own but in every attempt i hit a dead end. However, I learned Linux Administration from the very best. The quality and experience of the instructor are excellent and this reflects in his high quality post lecture hands on projects and assignments. I must also take this opportunity to thank the support staff for prompt doubt solving via their student forums. I am a permanent member of theirs and will continue to learn from Edureka.”

[@kumarcok]

Is wonderful video , just adding few more areas that may ask in interview . 1) about sudo (what is the use , how to configure , configuration file location etc.. ) 2.) How does the 'passwd' command gain root user permissions? 3) What is sticky bit and where it is used , how to set etc... 4) If we create an empty folder , it's size will be shown as 4K , why it so? 5) if /var filesystem became full , what will be your approach to solve this ? 6) why cant we set hard link between filesystems ? 7) how can we run a script while booting system itself ? ( before user login )

Hi Edurekha,, is this three videos are the complete Linux training?? My interest is to go towards cloud technologies but what should I do? What is the right path to choose? I’m working as a desktop engineer. Pls suggest

[@edurekaIN]

Hey Prashant, if you are looking to grow your career further in the cloud space then you should definitely enroll for our AWS Certification training program. Here is the link: www.edureka.co/cloudcomputing Hope this helps :)

[@prashanth2098]

edureka! But I’m new to the cloud, I don’t have any basic experience in that. So how can learn directly?

[@edurekaIN]

There are no specific prerequisites for participating in AWS training. Any professional who has an understanding of IT Service Management can join this training. There is no programming knowledge needed and no prior AWS experience required. We tend to teach right from the basics so that all our learners are at the same level, understanding wise. Thanks :)

[@prashanth2098]

edureka! Let me know the course duration and price.

[@edurekaIN]

Hey Prashant, you can check out our AWS Architect Certification training here: www.edureka.co/cloudcomputing The course has 30 hours of live instructor led online sessions with varying timings for different batches. The course price stands at: Rs 19,995/- Check out the other course details in the link above. You can mention your contact details and we will have one of our experts get in touch with you to discuss in details. Cheers :)
